title: AI Companion
---

You can create a personalised AI Companion using Mem0. This guide will walk you through the necessary steps and provide the complete code to get you started.

## Overview

The Personalized AI Companion leverages Mem0 to retain information across interactions, enabling a tailored learning experience. It creates separate memories for both the user and the companion. By integrating with OpenAI's GPT-4 model, the companion can provide detailed and context-aware responses to user queries.

## Setup
Before you begin, ensure you have the required dependencies installed. You can install the necessary packages using pip:

```bash
pip install openai mem0ai
```

## Full Code Example

Below is the complete code to create and interact with an AI Companion using Mem0:

```python
from openai import OpenAI
from mem0 import Memory
import os

# Set the OpenAI API key
os.environ['OPENAI_API_KEY'] = 'sk-xxx'

# Initialize the OpenAI client
client = OpenAI()

class Companion:
    def __init__(self, user_id, companion_id):
        """
        Initialize the Companion with memory configuration, OpenAI client, and user IDs.
        :param user_id: ID for storing user-related memories
        :param companion_id: ID for storing companion-related memories
        """
        config = {
            "vector_store": {
                "provider": "qdrant",
                "config": {
                    "host": "localhost",
                    "port": 6333,
                }
            },
        }

        2) Inquiring about the AI companions's capabilities or characteristics They may use words like "you" for this. 

        Respond with a single word:
        - 'user' if the input is focused on the user
        - 'companion' if the input is focused on the AI companion

        If the input is ambiguous or doesn't clearly fit either category, respond with 'user'.

        )
        return response.choices[0].message.content

    def ask(self, question):

    def get_memories(self, user_id=None):
        """
        Retrieve all memories associated with the given user ID.

        return self.memory.get_all(user_id=user_id)

# Example usage:
user_id = "user"
companion_id = "companion"
ai_companion = Companion(user_id, companion_id)

# Ask a question
ai_companion.ask("Ive been missing you. What have you been up to off late?")
```

### Fetching Memories

You can fetch all the memories at any point in time using the following code:

```python
def print_memories(user_id, label):
    print(f"\n{label} Memories:")
    memories = ai_companion.get_memories(user_id=user_id)
    if memories:
        for m in memories:
            print(f"- {m['text']}")
    else:
        print("No memories found.")

# Print user memories
print_memories(user_id, "User")

# Print companion memories
print_memories(companion_id, "Companion")
```

### Key Points

- **Initialization**: The Companion class is initialized with the necessary memory configuration and OpenAI client setup.
- **Asking Questions**: The ask method sends a question to the AI and stores the relevant information in memory.
- **Retrieving Memories**: The get_memories method fetches all stored memories associated with a user.

### Conclusion

As the conversation progresses, Mem0's memory automatically updates based on the interactions, providing a continuously improving personalized experience. This setup ensures that the AI Companion can offer contextually relevant and accurate responses, enhancing the user's experience.
